Abstracts common iteration operations on the input type

Associated Types

`type Item`

The current input type is a sequence of that Item type.

Example: u8 for &[u8] or char for &str

`type Iter: Iterator<Item = (usize, Self::Item)>`

An iterator over the input type, producing the item and its position for use with Slice. If we're iterating over &str, the position corresponds to the byte index of the character

`type IterElem: Iterator<Item = Self::Item>`

An iterator over the input type, producing the item

Required methods

`fn iter_indices(&self) -> Self::Iter`

Returns an iterator over the elements and their byte offsets

`fn iter_elements(&self) -> Self::IterElem`

Returns an iterator over the elements

`fn position<P>(&self, predicate: P) -> Option<usize> where P: Fn(Self::Item) -> bool,`

Finds the byte position of the element

`fn slice_index(&self, count: usize) -> Result<usize, Needed>`

Get the byte offset from the element's position in the stream
